Wrecked my TRP Spyre adjustment pads

bikegangster

Hi, I can't adjust the calipers on my brakes. The black circle that says "3mm in" isn't turning. I put in my allen key in the hole to screw it anti-clockwise to reset the brake pad position and I think I overdid it and damaged the hole. Now I can't screw it clockwise anymore to bring the pad closer to the rotor. Rubbish. I can't believe I ruined the best cable disc brakes out there. I am mad! I couldn't believe how fragile this thing is either. I was expecting them to be robust and strong but they're not when it comes to maintenance. What the hell. At least I can adjust the other side of the brake, I won't make the same mistake twice.

What should I do? I can't remove it and put in replacement adjustment pads. Should I take it to a mechanic and have him drill out the ruined adjustment pad or buy a brand new TRP Spyre? The Spyre's came with my Giant Defy 2016 as standard. Cheers.

Ham fisted home mechanic blames kit for ham fistedness shocker...

It's pretty simple in there but I'd take it to someone with a bit more mechanical sympathy to fix rather than carry on.

Actually, it's very very common. The insides have allen bolts which are very soft and freeze over time, hence the rounding. The solution is to remove the brake, take out the pads, ensure that everything is clean, lubed, moving well, then have a go. The distributor was happy to replace mine but with a note saying I needed to ensure that they remained clean at all times and dried off thoroughly.

Quite a few ham fisted people there.

Thanks for that. I've Spyres on 3 bikes and do my own fettling/application of hams They're a bit fiddly and I suppose if they've already seized, you're in trouble. Keep em serviced and go gently (as with most things on a boik) and they'll be fine. Apply force and they probably won't.

Update: Took it to Evans and explained what's wrong and they lend me a hex wrench. Turned the stubborn abjustment pad and it worked! Now I can bring the pad closer to the rotor! I was expecting the Spyre to break but it didn't. Turn the damn pad or destroy your Spyres, there's no other option.

What did I learn? Be gentle, especially when turning the pad anti-clockwise or else I lock it stuck again. Hex wrenches (or are they called T-handled Keys?) are harder than allen keys.
